Creative from: http://www.html5tricks.com/demo/html5-3d-cube/index.html, students give me a sample, feel very good, just can't think out the actual use. But the effect is very dazzling ~

：


Knowledge Points:

1, perspective, Transform's review

2, CSS3 Backgroud realize the background. The little princess on the surface

3, @-webkit-keyframes realization Animation


Html:

<body><div class= "Stage" >    <div class= "Cube" >        <div class= "Font" ></div>        <div class= ' back ' ></div>        <div class= ' left ' ></div>        <div class= ' right ' ></ div>        <div class= "Top" ></div>        <div class= "Bottom" ></div>    </div></ Div></body>

The previous 3D product show has already said how to make a cube, and that there are numbers on it. Theoretically more complicated than this, although the wood has this dazzle ~ here is not much to say.

Css:

 HTML {background:-webkit-radial-gradient (center, ellipse, #430d6d 0, #000000 100%);            Background:radial-gradient (ellipse at center, #430d6d 0, #000000 100%);        height:100%;            }. stage {-webkit-perspective:1000px;            Width:20em;            Height:20em;            left:50%;            top:50%;            Margin-left: -10em;            Margin-top: -10em;        Position:absolute;            }. cube {position:absolute;            width:100%;            height:100%;            -webkit-transform-style:preserve-3d;        -webkit-transform:rotatex ( -20deg) Rotatey ( -20deg); }. Cube * {background:-webkit-linear-gradient (left, Rgba (226, 248, 0.5) 0px, RGBA (54, 226, 248, 0.5) 3px, RGBA (0, 0, 0, 0) 0px),-webkit-linear-gradient (Top, Rgba (SI, 226, 248, 0.5) 0px, Rgba (SI, 226, 248, 0.5) 3p            X, Rgba (0, 0, 0, 0) 0px); -webkit-backgrounD-size:2.5em 2.5em;            Background-color:rgba (0, 0, 0, 0.5);            Position:absolute;            width:100%;            height:100%;            BORDER:2PX Solid Rgba (54, 226, 248, 0.5);        -webkit-box-shadow:0 0 5em rgba (0, 128, 0, 0.4);        }. Font {-webkit-transform:translatez (10em);        }. Back {-webkit-transform:rotatex (180deg) Translatez (10em);        }. Left {-webkit-transform:rotatey ( -90deg) Translatez (10em);        }. Right {-webkit-transform:rotatey (90deg) Translatez (10em);        }. Top {-webkit-transform:rotatex (90deg) Translatez (10em);        }. Bottom {-webkit-transform:rotatex ( -90deg) Translatez (10em); }

The same: stage as the arena. Cube sets the effect of the child element to 3d, and then each polygon rotates and sets the Translatez and then forms a cube.

Set the Backgroud code for each polygon:

     Background:-webkit-linear-gradient (left                ,                rgba (226, 248, 0.5) 0px,                rgba (SI, 226, 248, 0.5) 3px,                RGBA (0, 0, 0, 0) 0px),                        -webkit-linear-gradient (                top,                rgba (226, 248, 0.5) 0px,                Rgba (54, 226, 248, 0.5) 3PX,                rgba (0, 0, 0, 0) 0px);            -webkit-background-size:2.5em 2.5em;

Background settings, left-to-right 3-pixel strips, from top to bottom 3-pixel strips. Then set the background size to 2.5em 2.5em. The background is then displayed repeatedly. Effects such as the following (I added a border):



Today's full Effect:


Can see the cube has been formed, and finally added to the animation, do not think the animation is very complex, in fact very easy~

Define an animation frame:

@-webkit-keyframes spin        {            from            {                -webkit-transform:translatez ( -10em) Rotatex (0) Rotatey (0deg);                Transform:translatez ( -10em) Rotatex (0) Rotatey (0deg);            }            To            {                -webkit-transform:translatez ( -10em) Rotatex (360deg) Rotatey (360deg);                Transform:translatez ( -10em) Rotatex (360deg) Rotatey (360deg);            }        }

The name is spin. Start at Translatez ( -10em) Rotatex (0) Rotatey (0deg); At the end: Translatez ( -10em) Rotatex (360deg) Rotatey (360deg); That is, the same time around the X, Y axis 360 degrees rotation.

Finally, add this animation property to our cube:

  . Cube        {            -webkit-animation:6s spin linear infinite;            Position:absolute;            width:100%;            height:100%;            -webkit-transform-style:preserve-3d;            -webkit-transform:rotatex ( -20deg) Rotatey ( -20deg);        }

Set time for animation time 6s, animation spin, speed of uniform linear, infinite cycle infinite;

For more careful parameter setting, I will also write a blog that describes the properties of CSS3 separately after w3cschool~.



Well, the final effect is over.

For the original site look, there is a slight difference:

Since it adds a radial gradient to each of the polygons, we add:

    . Cube *:before        {            display:block;            Background:-webkit-radial-gradient (center, Ellipse, RGBA (0, 0, 0, 0) 30%, rgba (0, +, 0, 0.2) 100%);            Background:radial-gradient (ellipse at center, RGBA (0, 0, 0, 0) 30%, rgba (0,, 0, 0.2) 100%);            Content: ";            height:100%;            width:100%;            Position:absolute;        }

Take advantage of this pseudo-element of before and then set the radial gradient ~ ~ Now it's finally the same ~
